Christians claim that Jesus is God, who entered the world to die for the sins of man. We claim that this is a false belief, because this is a change on the part of God, and it is rationally impossible for a beginningless being to change. To prove this, we argue:
- Whatever has the potential to change, is inseparable from accidents.
- Whatever is inseparable from accidents, is emergent.
- Therefore, whatever has the potential to change is emergent.
Premise 1: Whatever has the potential to change, is inseparable from accidents
The first premise proposes that it is impossible for a being that can change, to exist without any accidents.
Accident: a quality that is other than the being it is attributed to. Such that, if this quality ceases to exist, it is not necessary for this being to cease to exist.
This premise is true, because “change” occurs when a being loses one accident, and acquires another. When the first accident ceases to exist, the second emerges into existence.
For example: a body that changes from rest to motion, transitions from being attributed with rest, to being attributed with motion. When rest ceases to exist, motion then emerges into existence.
Thus, change by definition, requires the changing being to be attributed with some accident. For if this being were not attributed with any accidents, then it would be impossible for it to lose an accident in order for change to occur.
Premise 2: Whatever is inseparable from accidents, is emergent
The second premise proposes that it is necessary for a being that is inseparable from accidents, to have emerged into existence.
This premise is true, because the set of all accidents is emergent. And since the being in question is inseparable from accidents, it could not have existed before the set of all accidents emerged into existence. Which means that this being’s existence is preceded by its non-existence (i.e. it is emergent).
The set of all accidents is emergent, because each accident is emergent, and the number of accidents that emerged into existence in the past is finite. Each accident is emergent because accidents exist contingently, not necessarily. For if their existence were necessary, then this would make it impossible for them to cease to exist. And if it were impossible for them to cease to exist, then those accidents wouldn’t be accidents. The number of accidents that emerged into existence in the past is finite, because each accident is an event, and it is impossible for an infinite number of events to have occurred in the past.
Therefore, whatever has the potential to change is emergent
The two premises are true, so the conclusion necessarily follows. Therefore, whatever can change, must have emerged into existence. And since God is beginningless by agreement, God is necessarily immutable. Which means that the incarnation is impossible.
 Consider the distinction between a body, and the motion of this body. If this motion ceases to exist, it is not necessary that the body cease to exist as well. Motion is therefore, said to be accidental for the body.
 As that would make it impossible for the being attributed with this accident, to exist without it. Whereas an accident is (by definition) a quality that accepts cessation, such that the being attributed with it can exist without it.
 Given the impossibility of Tasalsul. The completion of an infinite number of past events is impossible, because an infinity cannot be completed by definition. More on this here.
